摘要： Security devices which are difficult to reproduce include a grid screen metallization pattern. The grid screen metallization pattern may be laid down over a hologram or diffraction grating formed as a surface relief pattern on a substrate, to form a visually identifiable, semi-transparent security device. Additionally, the metallization pattern may include resonant structures in which information about the security device is encoded. In some embodiments of these security devices, the metallization pattern is disposed in accurate registration with the underlying hologram or diffraction grating. These security devices are made by methods which include printing an oil pattern on the substrate. Areas on which oil is deposited do not receive metal during a metallization step. Since these methods do not use caustics, metallization patterns including features which would otherwise trap and hold caustics are possible.

摘要： Microwave diffuser films are describe that provide a modified microwave energy field on one side of the diffuser film and on the other side. The films include an insulative substrate having a first side upon which is deposited a metallic coating capable of selectively reflecting a portion of incoming microwave energy. A coating is formed in a plurality of discrete areas having a predetermined reflectivity. The shape and spacing of the areas may be varied so that energy emission from noncoated surfaces of the substrate is spatially distributed in one or more ways; i.e. the energy emission more uniform than the energy impinging on the coated surface, the energy emission is focused on one or more particular location and/or the energy emission is shielded. A food packaging system for microwave cooking, which includes the microwave diffuser film of this invention, is also described.

摘要： A conductive structure for use in microwave food packaging which adapts itself to heat food articles in a safer, more uniform manner is disclosed. The structure includes a conductive layer disposed on a non-conductive substrate. Provision in the structure's conductive layer of fuse links and base areas causes microwave induced currents to be channeled through the fuse links, resulting in a controlled heating. When over-exposed to microwave energy, fuses break more readily than the conductive base areas resulting in less absorption of microwave energy in the area of fuse breaks than in other regions where fuses do not break. In this way the fused microwave conductive structure compensates for the uneven microwave field within a microwave oven and at the same time provides a safer conductive structure less likely to overheat. In addition, by varying the dimensions of the fuse links and base areas it is possible to design and fabricate different fused microwave conductive structures having a wide range of heating characteristics. Thus, a fused microwave conductive structure permits food heating temperatures to be tuned for food type.

摘要： A security device includes a holographic image observable in ambient light and through which a covert image is observable in a focussed beam of bright light, such as a flash light. The holographic image is coated with a metal layer of low optical density, while the covert image is produced by a metal layer of high optical density disposed away from an observer relative to the holographic image. The covert image may itself be amplified by positioning the high optical density layer on a layer of micro prisms.
